About

I build tools, write, speak, and teach about digital analytics, marketing technology, and privacy. My work includes the Digital Analytics Maturity Model (2009), WASP Inspector (2006, successful exit), gaAddons, and Da Vinci Tools (2017, successful exit). I'm also the author of The Art of Digital Analytics: Turning Imperfect Data into Better Decisions. Now I'm building MANTIS, an observability platform that helps analysts, developers, and privacy practitioners see what a website sends, identify the tools behind it, and investigate consent behavior with the evidence in view. Try the beta and tell me what would make your next audit easier.

After someone clicks “Reject all,” what do you check to verify their choice was respected?

Here s a test I d run in MANTIS. I d start with two fresh browser sessions, record the same page in each, and click Reject all in one and Accept all in the other. Then I d repeat the same action, like opening a product page, and Compare the captures.

If a GA4 request appeared after Reject all, I d open it in the request tree and check three things: what triggered it, what data it sent, and what consent state MANTIS observed when it fired. I d also check whether the browser stored or sent an analytics cookie. The request alone wouldn t tell me whether the choice was respected. The payload, cookies, and timing would give me a clearer picture.

What s the first thing you check after Reject all ? What would make you dig deeper?
